Introduction

Complement Factor B, also known as CFB, encodes complement factor B which is a component of the alternative pathway of complement activation. Factor B circulates in the blood as a single chain polypeptide. Once the alternative pathway is activated it is cleaved by complement factor D yielding the noncatalytic chain Ba and the catalytic subunit Bb. The active subunit Bb is a serine protease which connects with C3b to form the alternative pathway C3 convertase. Also, Bb is involved in the proliferation of preactivated B lymphocytes, while Ba inhibits their proliferation.

Description

CFB (26-259) Human Recombinant produced in E. coli is. a single polypeptide chain containing 257 amino acids and having a molecular mass of 28.4kDa. CFB is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.

Source

Escherichia Coli.
